Description

Technical field [0001] The present invention relates to the technical field of ductile iron material, and in particular, a balloon cast iron material for automotive hub and a preparation method thereof. Background technique [0002] The car wheel is an important part of the car, which is directly related to the operation of the car, so the quality and performance of the car wheel must be guaranteed. A key factor affecting the quality and performance of the car wheel is the hub material. More materials used to produce the production of automotive hubs, as the development of related process technology and the continuous emergence of new materials, the automotive hub material is constantly updating, and more and more superior material materials are applied in the car hub production, different Material, the corresponding production process is also different. [0003] The hub material can be coarsely divided into three major categories such as steel materials, alloy materials, composi...
